Mary, here is a link to Synthropol. It will save your quilt! I've used it in the past and cannot live without it. What it does is suspend the migrant dyes that bleed in the wash water and keeps them from redepositing on the lighter colored fabrics. Dharma Trading Co. is extremely reputable and has superb customer service. The small bottle would be perfect and will be at your door in a flash. I've ordered tons of stuff from them and always have it within a day or two.
note: I also have used their Professional Textile Detergent in place of Synthropol and it works just as well.
